' Specification of Letters Patent. Patented Sept, 29 1914 Application filed June 4, 1910. Serial No.564,938. i

To all whom it may concern:

Be it known that I, FRANK D. PownLL, of Lowell, in the county of Middlesenand State of Massachusetts, have invented certain new and useful Improvements in Carriers, of which the following is a specification.

My invention relates to carriers adapted for use in pneumatic despatch tube apparatus for the transporting of cash or 1nemo randa from the salesmans station to the cashier and the return of the same.

Figure l is a side elevation ofa carrier embodying my improvement' Fig. 2 is asimilar view of Fig. 1 with part of the shells and one of the heads in'section taken on the line 44 Fig. 4. Fig. 3 is a horizontal cross section taken on the line 55 Fig. 2. Fig. l is a perspective view of one of the shells of the carrier showing the star nut in its position on the shell. Fig. 5 is a plan view of the starnut. Fig. 6 is a similar view of the star nut after it has been formed up. I I

Like letters ofreference refer to like parts throughout the several views.

A represents a carrier provided with buffer heads D and E and rotatably telescopic shells B and C. These shells are adapted to be rotated to open up the interior of the carrier to receive money or memoranda after which the shells B and C are rotated to close the opening when the car. rier is in condition for despatch through the pneumatic tube.

The star nut F is blanked out by a punch press and is the shape shown in Fig. 5, after which it is formed up into a flaring shape on a punch press as shown inFig. 6. The flaring shaped star nut is then placed onto the inner side of the felt head and struck with the punch press, and owing to the shape of the teeth G as shown in Fig. 6 they will spread out under the blow and lock themselves into the felt and assume the position shown in Fig. 2.

The shells B and C are provided with" projecting prongs H which correspondingly number to the spaces between the teeth G of the star nut as shown in Fig. 4. As the star nut and teeth H are similar on both ends it will be sufllcient to describe simply one of these arrangements which is illustrated in Fig. 2. These prongs H fit in between the prongs G of the nut F after it has been fixed into the felt head as indicated n Fig. 2. After the buffer D has been attached to the shell O a metallic washer J is brought up intodirect contactwith the star nut F and the same are firmly held in contact with one another by a suitable screw F. This direct contact of the two metals is advantageous in thatit avoids the breaking of (the screw nuts which is apt to take place whenjfelt or othermaterial is inserted betweenthetwo pieces of metal. Bymeans of "my invention solid felt heads can be used; also attachment ofthe head to the shells is greatly simplified. The construction preventsthe feltfhead from turning, owing to the engagement of the prongs with the metal star nut which is forced into the felt head. The star nut bearing tightly against the inner metallic washer holds the felt head rig idlyto the carrier shells and prevents any end or longitudinal movement of the head- The metallic star nut isfirmIy held in the felt head owing to its being driven therein under pressure. The prongs fit snugly between the teeth of the star nut and are held rigidly in position by means of the screw F which tightens the buffer head and holds it tight down on the shell. The location of the prongs betweenthe teeth also. provides for taking up the twisting strain on the buffer heads for opening and closing the shells.

Having thus described the nature of my invention and set forth aconstruction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a carrier, a buffer head provided with a metallic member embedded therein and having spaced teeth,a shell provided with prongs adapted to pass between the teeth of said metallic member, and means for securing said shell to said buffer head.

2. In a carrier, a buffer head provided with a flaring metallic member embedded vided with prongs adapted to pass between i the teeth of metallic member, and means for securing said shell to said buffer head.

3. In a carrier, a. buffer head provided with a metallic member embedded therein, shell to which said bu-fl'er head is adapted to be secured, a washeradapted tobe brought into contact with said metallic member, and means for securing the washer in direct con- .thereof adjacent said shell, said material substantially completely covering and con cealing said member, and means for firmly] seeuringsaid member to saidshell.

5. A carrier comprising a shell, a buffer head ofcushioning material, for said shell,] andlmeans for rigidly uniting said cushion-l ing material to said shell, said means in eluding a plurality of spaced apart, de-t formed prongs wedged into said material from the side thereof adjacent said shell,

said deformed prongs being subjected, at least n tially, to greater pressure from. said material upon one SlClQ' of each of said prongs than upon an opposite side of the;

same and beingdeit'ormed by being thus Copies ofithis patent may be obtained for wedged into said material so as to grasp said material in the interior thereof.

6. A carrier comprising a shell, a buffer head of cushioning material and means for firmly uniting said buffer head to said shell, said means comprising parts driven into and adapted to grasp said material in the interior thereof, substantially all parts of. said means being concealed by said material and the latter being integral. throughout.

7. A carrier comprising a shell provided with a bulter head of yielding cushioning material having attached thereto a pronged member, the prongs of which are driven into said cushioning material and deformed by the unequal lateral pressure exerted thereagainst by said material when being driven thereinto.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 1st day of June A. D. 1910.
